Plot[]
On Halloween at the Vuuugle House, Paige, Frankie, Amelia, Bernie, Zane, and Rodney forgot to get candy for the trick or treaters and instead tell them three Halloween stories. The first story has Paige and Bernie in a Victor Frankenstein and Igor-type role where they plan to place a genius brain in Frankie for Coach Carlson's science assignment only for Bernie to unknowingly obtain a monster brain since the genius brain is not on sale yet. This causes Frankie to act like Frankenstein's monster before eventually being changed back. In the second story, Zane has undergone an operation to replace his hands with scissors, believing that it will make him a better unboxer. After giving Rodney a haircut, the hair comes to life and terrorizes them, Amelia, and Bernie. When the hair morphs into a giant hair monster, Rodney uses hairspray that gives his hair the ability to attack and destroy the monster. The third story has Bernie discovering a portal in the Vuuugle House's foam pit that takes him to an alternate dimension where everything is made of foam. Paranormal expert Dr. Duckworth helps Paige, Frankie, Zane, and Rodney rescue Bernie, but they learn that he has been made king of the foam world and has no desire to leave.
